Abstract

The invention relates to a tank mix spray additive containing rhamnolipid as well as a preparation method and application thereof, and belongs to the technical field of pesticide additives. The tank mix spray additive containing rhamnolipid is composed of the following components in percentage by mass: 5-50% of a rhamnolipid solution; 0-25% of a chemical surfactant; 0-25% of a cosolvent; 0-5% of a pH regulator; the total percentage is 100%. According to the invention, the biological surfactant rhamnolipid is used for replacing or reducing the dosage of a chemically synthesized surfactant in the tank mixing auxiliary agent, so that the environmental safety of the tank mixing auxiliary agent is improved, residues and environmental hazards are reduced, the physicochemical properties of pesticide liquid during use can be changed, the pesticide effect of the pesticide liquid can be improved, and the dosage of the pesticide liquid can be reduced.

Description

technical field [0001] The invention relates to the technical field of pesticide adjuvants, and specifically provides a rhamnolipid-containing tank-mix spray adjuvant as well as a preparation method and application thereof. Background technique [0002] With the continuous tightening of ecological and environmental protection policy requirements and the continuous improvement of people's awareness of food safety, the contradiction between the policy requirements of double reduction of pesticides and chemical fertilizers and the increasing accumulation of resistance to agricultural diseases, insect pests and weeds has become increasingly prominent. Therefore, it is necessary to seek technical means to solve this problem from various aspects, so as to realize the reduction of pesticides and chemical fertilizers and their efficiency. [0003] In order to improve the targeting and control effect of pesticide application, tank mixing adjuvants can be added to improve the physical...
